I have my Red Wings which I love when I'm climbing and they're not all that bad working on the ground with either. However, they aren't water proof and they are expensive so I wanted a "daily driver" boot I can wear when the weather nasty or I'm just riding around in the bucket all day. I started buying the 8" timberland with a steel toe for around 120. Not only are they great on pavement but they are surprisingly comfortable to climb with and their soft soles grip the tree pretty good. The downside is that they are a 100 dollar boot, so dont expect years of service out of them, that and they only come in tan, which isn't my favorite color for work boots.
If you are looking for boots comfortable to climb with in the 100 dollar price range these are hard to beat, that and they are almost always on sale at Sears.
